As the topic says they really need some better healing, the medic truck is a nice feature but it should be an alternative also you get it very late (after you have all 3 buildings), this does not work well on low fuel maps.
I really like the no retreating but i don't really understand why the red army can't crew, build OPs or medic stations, the Russians were known for using captured weapons against the germans and your american/british friends can still do all those things and with all the dead conscripts that really gives the allies a big advantage.
And no veterancy would really just make it boring and less tactical when its barely worth keeping units, it doesn't have to give huge bonuses to make them invincible just small ones like increased grenade range.
A nice feature would be if molotovs could damage the engine on small tanks.
Also some popcap and unit costs could use a rework like the outpost is too expensive and katyusha is too cheap
Other than that great mod, keep it up!
edit: read about recrewing so nevermind that.
